“It’s going to be a way for us to interact with the world around us without having to constantly identify ourselves,” Ulanoff explained.

Bionym, a Canadian company, developed a wristband to recognize the pattern of an individual pulse. The wristband transmits information that allows the user to do things like withdrawing money without a bank card.

“You don’t have to remember anything. You don’t have to do anything special,” Ulanoff said.

Bionym isn’t the only company developing concepts that use the human body as a form of identification. Motorola is working on a temporary tattoo that contains a computer chip and an antenna.

A pill that dissolves and turns the entire body into a transmitter is also in the works.
